Energy is needed to move sugar from low to high concentration while using a membrane protein.
Explanation:
The reason that energy is needed in this process is that the movement of the molecules is moving up the concentration gradient. This means decreased entropy and increasing Gibbs's free energy.
This is not a spontaneous process and therefore energy input is required. It is called active transport. This is why ATP energy is used to power the process. Atp enables the transmembrane proteins to change conformation and transport the sugar molecules into the cell.
In facilitated diffusion, while the molecules are facilitated by membrane proteins, no energy is input because the molecules are still traveling down the concentration gradient.

The sequence of mRNA for a DNA strand AACGTAACG will be UUGCAUUGC.
Central dogma can be described as a process by which information in the DNA is transcribed into mRNA and then changed into proteins.
For a strand of DNA, a complementary mRNA strand is made in order to decode the information in this strand of DNA into mRNA.
The pairing is done as follows: Adenine pairs with Uracil, and Guanine pairs with Cytosine for forming the mRNA transcripts. The nucleotide thymine is absent in mRNA.
Hence, for the strand AACGTAACG, the mRNA strand will be UUGCAUUGC.

Immune system becuase ur immune system helps get rid of sickneess
Answer:
C
Explanation:
pyruvate dehydrogenase is the enzyme which catalysis pyruvate to acetyl Co -A. Thus,it ensures the formation of link reaction/ bridge reaction for linking glycolysis with Citric acid cycle. Therefore, inhibition of this enzyme, prevent link reaction, and there reduction in pyruvate utilization and therefore prevent the commencements of Citric acid cycle, with consequent reduction in glucose oxidation. as there is no reaction of acetyl Co A (from link reaction from pyruvate ) with 4C oxaloacatate in the kreb Cycle to form Citrate in Kreb's cycle. Thus the heart depends on fatty acid supply for energy.
Answer:
Polar
Explanation:
In a water molecule, the oxygen atom is bigger and has a greater pull on the electrons than the hydrogen atoms do. This makes the molecule polar.
